Ecotourism has developed fairly spontaneously and irregularly in Russia. Some territories experience heavy pressure, while others, quite interesting as well, are not visited by tourists. An evaluation of ecotourism development potential was accomplished for every administrative region of the Russian Federation. Adjacent regions with similar ecotourism potential were combined into ecotourism regions. Thirty ecotourism regions can be delineated on the territory of Russia. They are shown on a map of 1:30 M scale. The factors that specify the separation of these regions are described. The ecotourism potential of the regions is compared with the offer of eco tours on the Internet. Coincidence and convergence are marked out and construed; recommendations are made on further development of ecotourism.
